It seems to me, if gun manufacturers faced a financial or legal disadvantage to guns being used illegally, then they'd be more likely to find some way to make that more difficult. I don't know how, exactly, maybe a fingerprint scanner like some cell phones have, making it only possible for the registered owner to operate them, something like that (not a gun guy, if that isn't obvious).
But if guns being used illegally is financially advantageous for gun manufacturers (more guns stolen means even more guns are bought to replace them, cha-ching!), then there's no incentive to even try to make it harder to use guns illegally.
-- A2SG, I realize my example above is probably wildly impractical, if not impossible...so please refrain from explaining exactly why......as I said, not a gun guy.....
